Pi began as the 16th letter in the Greek alphabet, and looked like this: π. Now, we know Pi as the ratio of a circle's circumference to it's diameter. Pi is one of the most important mathematical equations needed in science and engineering. Pi, as a decimal, looks like this: 3.14159265358979323846...
Notice the symbol after the last numeral. That indicates that pi is an irrational number. That means that it does not a determined ending, and also that the numbers follow no certain pattern. In other words, in Pi, you will never see the same string of numbers twice.
A brief history of π
The symbol "π" is originated from the Greek word "περίμετρος" (meaning perimeter). As I have already mentioned, Pi started out as a Greek letter, however many people wondered about how to show an unending decimal like 3.1415926535897932346... So, many people began to associate the letter π with this decimal, and then the circumference of a circle (however, it is still possible to write it as 3.14, but it is more accepted as π).
